The charity direct marketing agency Whitewater has gone into administration, along with Involve (formerly JDA).
UK Fundraising understands that announcements were made at both the companies involved this morning (Monday 16 April).
Whitewater had been part of the group since 2007 and had specialised in charity direct marketing since its inception in 1987. According to its website, clients included Macmillan Cancer Support, RNLI, Royal British Legion and RSPCA.
A statement from Martin Smith, ceo Involve Marketing Partnership, said that the move had no effect on other business and agencies in the Group.
